摘要：

This paper describes a proposal of a new magnetic fluid analysis method to calculate the coupling problem of electromagnetic field and flow field with free surface using two-dimensional finite element method. First, it introduces a formulation of electromagnetic and flow field. In order to solve a flow field problem, level set method is employed. Second, experimental verification is shown through the comparison of calculated and experimental results when moving magnetic field is applied. The measured displacement qualitatively well agreed with the calculated. Finally validity of the analysis method is discussed. © 2012 The Institute of Electrical Engineers of Japan.
